Complementary follow-upAskabide + Osakidetza · birth at the reference hospital
Maternal and fetal checks
- Blood pressure and symptoms.
- Fetal growth and biometry when indicated.
- Fetal presentation, placenta and amniotic fluid.
- Fetal movements and wellbeing in context.
- Review of laboratory results and risk factors.
Third-trimester ultrasound
This may assess growth, presentation, placenta, fluid and other parameters. Doppler is used when clinically indicated or included in the relevant examination protocol.
Askabide protocol from week 36
We may include weekly cardiotocography from week 36. The recording observes fetal heart rate and uterine activity during a defined period. A reactive trace is reassuring for the recorded period, but it does not guarantee future progress.
Frequency is individualised and monitoring does not replace hospital assessment when there are symptoms, risk factors or findings.
